Abstract
The invention discloses a pair of dot dash line compasses. The pair of dot dash line compasses comprises a flanged wheel, a lead refill sleeve, a lead refill, a guide wheel, a lead refill seat, a lead refill sleeve foot, a locking screw, an ordinary compass general part, slide blocks, a universal ball and a spring. By using the pair of dot dash line compasses, dot dash line circles can be drawn conveniently. The operating method of the pair of dot dash line compasses is the same as that of ordinary compasses.
Description
Technical field
The present invention relates to a kind of stationery, particularly relate to a kind of chain-dotted line compasses.
Background technology
Present manual drawing chain-dotted line bowlder, uses common compasses need to allow lead for retractable pencil interval graphical pointv and circular arc, operates more loaded down with trivial details, draws poor effect.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of chain-dotted line compasses.
The present invention is achieved through the following technical solutions
A kind of chain-dotted line compasses comprise flange pulley, lead core cover, lead for retractable pencil, directive wheel, lead for retractable pencil seat, lead core cover pin, lock-screw, common compasses general part, slide block, multi-directional ball, spring, wherein directive wheel is installed on the outside of lead core cover pin, it is coaxial with directive wheel that inner side is provided with flange pulley, lead core cover pin has endoporus, slide block top is provided with spring and is together placed in the endoporus of lead core cover pin, be provided with multi-directional ball on the downside of slide block, lead for retractable pencil seat is fixed on slide block, loads lead for retractable pencil and install lead core cover on the downside of it;
It is characterized in that directive wheel is relative with flange pulley fixing, flange pulley outline is the convex-concave profile of rule, and directive wheel rotates can drive flange pulley synchronous axial system, and slide block pushes away downwards by spring, make the multi-directional ball on the downside of slide block press the outline of flange pulley, multi-directional ball can be rolled along flange pulley outline.
The invention has the beneficial effects as follows: use the present invention, chain-dotted line circle can be drawn with common compasses method of operating is identical, draw the convenient and specification of chain-dotted line circle than common compasses.
Accompanying drawing explanation
Fig. 1 is figure of the present invention
Fig. 2 is partial sectional view of the present invention
Fig. 3 is broken section enlarged drawing of the present invention
In figure, flange pulley 1, lead core cover 2, lead for retractable pencil 3, directive wheel 4, lead for retractable pencil seat 5, lead core cover pin 6, lock-screw 7, common compasses general part 8, slide block 9, multi-directional ball 10, spring 11.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing:
As shown in Figure 1-Figure 3, a kind of chain-dotted line compasses comprise flange pulley 1, lead core cover 2, lead for retractable pencil 3, directive wheel 4, lead for retractable pencil seat 5, lead core cover pin 6, lock-screw 7, common compasses general part 8, slide block 9, multi-directional ball 10, spring 11, wherein directive wheel 4 is installed on the outside of lead core cover pin 5, it is coaxial with directive wheel 4 that inner side is provided with flange pulley 1, lead core cover pin 5 has endoporus, slide block 9 top is provided with spring 11 and is together placed in the endoporus of lead core cover pin 6, multi-directional ball 10 is provided with on the downside of slide block 9, lead for retractable pencil seat 5 is fixed on slide block, loads lead for retractable pencil 3 and install lead core cover 2 on the downside of it;
In addition directive wheel 4 is relative with flange pulley 1 fixing, flange pulley 1 outline is the convex-concave profile of rule, directive wheel 4 rotates can drive flange pulley 1 synchronous axial system, slide block 9 pushes away downwards by spring 11, make the multi-directional ball 10 on the downside of slide block 9 press the outline of flange pulley 1, multi-directional ball 10 can be rolled along flange pulley 1 outline.
The course of work of the present invention is: above-mentioned chain-dotted line compasses are at picture bowlder, directive wheel 4 rolls along paper and drives flange pulley 1 synchronous axial system, multi-directional ball 10 is rolled along flange pulley 1 outer rim, slide block 9 is moved up and down with the fluctuating of flange pulley 1 outline under the effect of spring 11, the lead for retractable pencil seat 5 be fixed on slide block 9 drives the regular motion of lead for retractable pencil about 3, lead for retractable pencil 3 just with the Intermittent Contact of paper in draw chain-dotted line circle.
